Flappy Cow is an Android game in "Flappy Bird" Style. Since Nguyen Ha Dong, the developer of "Flappy Bird", anounced the end of his loved but also hated game I uploaded this Open Source game, so you have an alternative to fulfill your addiction.
Initially called Flappy Cow, it has now(v.1.83) been renamed to FlutterCow because of Googles policy on the word Flappy in app names
